COAL-=CLEANER.

@473 forming part of Letters Patent No, 308,206, dated November 18,1884.

Application tiled. May 2-2, 1894. (No model.)

I; (1.77 whom, it may concern it known that 1, WILLIAM Homer Siren 1111121), of l iilston, in the county of Luzerne and State of Pennsylvania,have invented a new and Improved Coul.-0leaner, of which the followingis a full, clear, and exactdescription.

The object of my invention is to provide a new and improved machine forseparatingthe slate and rocks from coal by means of screens and acurrent of air.

The invention, which is an improvement on Letters Patent No. 291,788,issued to me on the 8th day of January, 1884, for an improvedcoal-cleaner, consists in various parts and combinations of the same, aswill be fully hereinafter described and claimed.

Reference is to be had to the-accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding partsin both the figures.

Figure 1 is a longitudinal elevation of my improved coal-cleaner, partsbeing broken out. Fig. 2 is a plan view of the same, parts being brokenout. Fig. 3 is a longitudinal vertical section on line 3 yofFig. 2. Fig.4is atransverse vertical section on line 00 as of Fig. 3.

The coal is delivered on an inclined chute, A, and slides down the sameupon the two screens B, formed of a series of longitudinal inclinedgrate-bars, a, secured edgewise on cross-bars G, and between the saidbars at bars 1 are secured at their lower edges in the upper edges oftransverse beams D, placed and secured edgewise on transverse bars E,under the frame or box F, in which the barsO are secured. The bars E aresecured to the lower ends of two pairs of rods, G, held to slidevertically in perforated guide-lugs H on the outer sides of the box F.The upper ends of the rods G are united in pairs by bars I I, which areconnected by rods J J with the ends of walking-beams K, pivoted on theupper ends of standards L, secured on the sides of the box F. Both sidesof the box are constructed in the manner described. The walkingbeams Kare connected by a rocking shaft, M, journaled in the standards L, whichshaft is provided with an upwardly-projecting arm, L, connected by arod, N, with a crank-wheel, O, mounted on a shaft, 0, journaled in theupper end of a standard, P, which shaft is provided at one end with acrank, P, or other device for revolving it. The pulley or crankwheel 0is grooved, and around it a driving belt or cord, Q, passes, which alsopasses over a pulley, R, of a blower or fan, R, held on onestandard,P,and provided with a downwardlyprojecting neck, R, which leadsto a transverse tube, S, provided on its rear with a spout, S, extendingthe entire length of the said tube.

On a transverse beam, 7, uniting the standdards P, an inclined apron, T,is hinged, which is located above the tube S and has its free edgeinclined downward. The apron T rests on two cams, I, mounted rigidly ona transverse shaft, U, journaled on the standards P, and is providedwith a handle, m. Below and in rear of the apron T a chute, V, isarranged, the bottom V of which extends from the rear. of the chute to apoint a short distance in rear of the outer edge of the apron T, wherebya slot, V, or opening is formed in the bottom V of the chute V.

The operation is as follows: The coal slides from the chute A upon thescreens B, the bars 9 of which are worked up and down and cause thecoals to slide down the screens B upon the apron T. As the coals slidedown the screens, the flat pieces of scale and slate drop down betweenthe bars a and g. The coals slide down the apron T and jump from thefree edge of the same upon the bottom V of the chute V. The coals, beinglighter than the rocks, &c., pass over the opening \V upon the bottom V;but the rocks, which are heavier thanthe coals, drop through the slot W.and coals I have provided the blower, which delivers a powerful currentof air under the apron,which assists in carrying the coals from the endof the apron upon the bottom V of the chute, but does not affect therocks which are too heavy. By means of the cams Z the free end of'theapron can easily be adjusted higher or lower, according to the speed thecoals are to have in sliding over the apron T.

.Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

To facilitate this separation of the rocks 1. In a coal-cleaner, thecombination, with substantially as herein shown and described.

a chute, of screens, an apron below and in rear of the lowest screen, achute in rear of and below the apron, which is arranged to leave a slotextending from side to side of the apparatus below the free edge of theapron, substantially as herein shown and described.

2. In a coal-cleaner, the combination. with two screens, each composedof alternate stationary and reciprocating bars, and an apron hingedbelow and in rear of the lower screen, of the fan-blower R, providedwith the downwardly-projecting neck R and the transverse tube S,extending the whole length of said tube, substautially as herein shownand de scribed.

3. In a coal-cleaner, the combination, with the screens B, of the apronT, hinged below and in rear of thelowest screen, the fan-blower R, andthe chute V, provided with a trans verse slot below the free edge of theapron,

4. Ina coal-cleaner, the co1'nbinati0n,.with the screen B, composed ofthe stationary and movable bars cg, of the walking-beams K, the shaftsM, provided with the arm L, the con necting-rod N, the groovedcranlcwheel O, the belt Q, the pulley Rbon the shaft of thefi'tD-blOWGl, and intermediate mechanism for connecting thewalking-beams to the movable bars of the screens, substantially asherein shown and described.

5. In a coal-cleaner, the combination, with a chute and screens, of anapron hel'd below and in rear of the lowest screen, the shaft U, belowthe apron, the cams Z on the shaft U, and the handle in on the end ofthe same, substantially as herein shown and described.
